STORM-1945 Fix NPE bugs on topology spout lag for storm-kafka-monitor
* Fix several spots which are throwing NPE on TopologySpoutLag
* Use a trick to get classname of Spout without requiring storm-kafka and storm-kafka-client
* Move storm-kafka-monitor jar to toollib directory
* since jars in extlib are added to worker classpath which we don't want for this jar

>
> When opening topology page which uses old storm-kafka Spout, page shows Internal Server Error on bottom side.
> And REST API /api/v1/topology/:topology/lag also shows Internal Server Error.
> Its errorMessage is describing NPE, but stack track gives less help since it's already within catch statement so we can't trace why origin exception is thrown by only looking at errorMessage. And there's no error message on ui log file.
